I just upgraded to 12.04. As the machine boots, it seems to connect to
the network since I can ping to IPs, however it cannot resolve DNS. In
other words if I do "ping google.com" it would say "unknown host
google.com". Please let me know what kind of specific information you
may need.
Thanks,
Daniel
